What is the density of an object with a mass of 60g and a volume of 2 cm 3?
Terms in this set (36) What is the density of an object with a mass of 60 g and a volume of 2 cm (3)? Mass=48 g; volume= 24 cm (2).
How do you find density when given mass and volume?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
What is the density of a 40 gram object whose volume is 20 mL?
Density = mass /volume = 40/20 = 2g/mL.
What is the density of an object that is 100 grams and has a volume of 5 cubic centimeters?
What is the density of and object that is 100 grams and has a volume of 5 cubic centimeters? J. 20 g/cm.
What material of mass 39g has a volume of 5 cm 3?
Answer. So, the material of density 7.8 g/cm³ is the answer.
How do u calculate mass?
To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons. In the formula for determining mass based on weight, mass is measured in Newtons.
What is the formula of mass and weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is formula of atomic mass?
The formula for atomic mass is given below. Atomic mass = Mass of protons + Mass of neutrons + Mass of electrons.
What is the difference between mass and weight?
The mass is essentially “how much stuff” is in an object. Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).
Does mass depend on weight?
Mass is independent of gravity and is therefore different from weight. See Note at weight. An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.
What is the weight of a body of mass 1 kg on earth?
Since g=9.80m/s2 g = 9.80 m/s 2 on Earth, the weight of a 1.00-kg object on Earth is 9.80 N: w=mg=(1.00kg)(9.80m/s2)=9.80N. w = m g = ( 1.00 kg ) ( 9.80 m/s 2 ) = 9.80 N . When the net external force on an object is its weight, we say that it is in free fall, that is, the only force acting on the object is gravity.
What is the weight of a 1 kg mass on the moon?
On the Moon, g = 1.6 N/kg. In other words, a 1 kg mass has a weight on the Moon of 1.6 N….Summary.
| Mass | Weight |
|---|---|
| Measured in kilogrammes kg | Measured in newtons N |
| A measure of the amount of matter | The force of gravity acting on the object |
Can a body have zero mass?
A physical body cannot have zero mass. Since the weight of a body depends on the gravitational field, a body with the same mass can have different weights at different places. The weight of a massive object can even be zero.
Where is the true weight of the body zero?
The true weight of a body will be zero where the gravitational effects are nil e.g. at the centre of Earth or deep in space far away from the given star or planet.
In which condition can a body with fixed mass have zero weight?
Weightlessness
Can a body have zero mass and non zero weight?
It is not possible for a body to have zero mass ( no body can exist without mass ) but a body can have zero weight….. Weight = Mass × Gravitational acceleration. At the center of the earth the gravitational acceleration is 0 so multiply 0 with mass and any no. multiplied with 0 is 0 so weight can be 0.
What is the weight of a body during free fall?
A freely falling object has weight W=mg, where W-weight, m-mass of the object and g-acceleration produced due to the earth’s gravity. An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg.
What is more likely an object with 0 or 0 weight?
It is more likely for an object to have a weight of zero because the weight is the measure of the gravitational force on an object. It is possible to weigh nearly 0 in outer space. Matter, however, is the measure of matter in an object.
Who is mass?
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object’s mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).
Does zero gravity exist?
Contrary to popular belief, there’s no such thing as zero gravity. Weightlessness and zero gravity are two different things. The earth’s gravity keeps the moon in orbit. And astronauts are generally much closer to earth than the moon is, which means that the earth’s pull on them has to be much stronger.
Why weightlessness is called Masslessness?
Q. Can the condition of weightlessness be called masslessness? → No, its don’t called masslessness. Because during weightlessness objects seems weightless only but actually its weight (pulling force) and mass of object remain.
What is meant by free fall?
In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement.
How does weight affect free fall?
The mass of an object does not depend on the location, the weight does. An object that moves because of the action of gravity alone is said to be free falling. So all objects, regardless of size or shape or weight, free fall with the same acceleration.
When a body is under free fall?
chandra’s post “Free fall means when there is only one force actin…” Free fall means when there is only one force acting on the body which is the gravitational force.
How do you calculate time it takes for an object to fall?
Measure the distance the object will fall in feet with a ruler or measuring tape. Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.
Does mass affect free fall?
“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. Free fall occurs whenever an object is acted upon by gravity alone.
